Hi there,

i recently installed CentOS 6 64bit version on my HPProBook4530s Laptop. After running full system update and system restarted, my touch pad is not responding any more. How can i fix this problem?

Kind Regards

    Implication is that it was working before the update?
    If so, reboot and load the prior kernel (select from grub menu)
    Then can use lsmod to show what drivers are loaded, although if it is a precomipled driver it does not show. A reboot into the new kernel and a compare of the lsmod results should show the missing driver. If it is pre-compiled into the kernel, one will need to examine the kernel source docs to see what they changed – this will need help from someone else as I’ve only done this twice and it takes some steps that I
    do not recall. HTH

  • Thanks for reply.
    1- yeah touch pad was working before i applied system updates.

    My old config was as follows

    >uname -a

    Linux localhost.localdomain 2.6.32-71.el6.x86_64 #1 SMP Fri May 20
    03:51:51 BST 2011 x86_64 x86_64 x86_64 GNU/Linux

    Hi, nothing leaps out at me – although I do note i915 is included in the later kernel modules – this chip is involved in the graphics and thus the X.org / X11 part of your setup – thus you may want to look through dmesg output and determine what kind of touchpad your laptop has. For synaptics this page may help http://www.thinkwiki.org/wiki/Synaptics_TouchPad_driver_for_X
    You will see that X.org is intimately involved with this and may well be the issue you have. Are you using default graphics card drivers? – sometimes changes to the kernel make X miss-behave. Try to use kmod aware drivers from elrepo –
    it makes life so much easier. http://elrepo.org/tiki/About Check out your /etc/X11/xorg.conf HTH

  • can we please trim messages when replying. I don’t think it was neccessary to send the whole original message with all its kmod dumps as well as 3 copies of the list tailer to say ‘thank you’ to Rob’s one paragraph response.
